Firmware and Configuration File
Maintenance
This chapter tells you how to backup and restore your configuration file as well as upload
new firmware and configuration files.
31.1 Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings in
the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a
“rom” filename extension. Once you have customized the HomeSafe's settings, they can be saved
back to your computer under a filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the
system firmware and has a “bin” filename extension. With many FTP and TFTP clients, the
filenames are similar to those seen next.
)
Only use firmware for your HomeSafe’s specific model.
Refer to the label on the bottom of your HomeSafe.
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the
HomeSafe.
ftp> get rom-0 config.cfg
This is a sample FTP session saving the current configuration to the computer file “config.cfg”.
If your (T)FTP client does not allow you to have a destination filename different than the source,
you will need to rename them as the HomeSafe only recognizes “rom-0” and “ras”. Be sure you
keep unaltered copies of both files for later use.
The following table is a summary. Please note that the internal filename refers to the filename on
the HomeSafe and the external filename refers to the filename not on the HomeSafe, that is, on
your computer, local network or FTP site and so the name (but not the extension) may vary. After
uploading new firmware, see the ZyNOS F/W Version field in Menu 24.2.1 – System
Maintenance – Information to confirm that you have uploaded the correct firmware version.
The AT command is the command you enter after you press “y” when prompted in the SMT
menu to go into debug mode.
